BRENTWOOD — An attorney representing the four police officers who were wounded during a drug raid in Greenland last year has asked the state to hand over the bullets that struck two of the men.

Portsmouth Attorney Christopher Grant is requesting for the attorney general's office to provide the wounded officers with a variety of evidence related to the April 12, 2012, shooting.

Greenland Police Chief Michael Maloney was shot dead and four members of the Attorney General's Drug Task Force were wounded during the operation.

Several months later, the four wounded officers sued the mother of shooter Cullen Mutrie, claiming she “recklessly and wantonly” allowed her son to carry out a criminal enterprise at the home where the drug raid occurred, leading to their injuries.

The home, located at 517 Post Road, is owned by a trust Beverly Mutrie controls, according to court records.

In the wake of the shooting, New Hampshire State Police conducted a comprehensive investigation documenting the circumstances surrounding the shootings. The findings were released in December.

Among the documents included in the 3,000-plus page state police investigation report is a letter sent to Grant by Associate Attorney General Jane Young on Sept. 11. In the letter, Young described a previous request submitted by Grant for the state to “preserve and return” the bullets removed from the bodies of Newmarket Detective Scott Kukesh and Rochester Detective Jeremiah Murphy.

In response, Young wrote that the state would honor their request and return the bullets at the conclusion of the investigation.

With the investigation now completed, Young filed a motion in Portsmouth Circuit Court last week asking a judge to grant permission for the state to return “numerous” items seized from the police officers involved in the incident. A judge signed off on the request Tuesday.

“Typically, when cases are concluded, any evidence that comes into our hands, a motion is made either to destroy it or to return it to the owner,” Young said Tuesday. “That's a basic sort of motion that's filed at the conclusion of cases.”

The attorney general's office filed a similar motion to return evidence to the parents of Brittany Tibbetts a few months ago.

Tibbetts, a 26-year-old Maine resident, was killed by Mutrie during the course of a lengthy standoff with police.

In September 2012, the attorney general's office was granted permission to return a watch, three rings, two earrings and three piercings to Tibbetts' family, according to court records.

“It's not uncommon for families or individuals who have had items taken during criminal investigations to have them returned,” Young said.

Grant declined to comment on his intentions for the bullets during an interview last week.

However, the evidence could be pertinent in the pending civil lawsuit.

The plaintiffs claim Beverly Mutrie facilitated her son's criminal activities by allowing him to live in her house, drive her cars and receive her financial support.

Rockingham County Superior Court Judge Kenneth McHugh has dismissed a majority of the lawsuit, indicating the plaintiffs failed to establish that Beverly Mutrie's financial and material support for her son created a harmful situation for others.

“Providing him with a house, cars and financial assistance did not enable Cullen Mutrie to shoot the police, nor did it contribute to his decision to do so,” he wrote in October.

However, McHugh left open the possibility that Beverly Mutrie created a potential risk to others by allowing firearms to come into her son's possession.

One of the two handguns seized from the home at 517 Post Road in the wake of last year's shooting was purchased by Cullen Mutrie's father, according to the attorney general's office.

The four police officers, through their attorney, argue the weapon was likely transferred to Cullen Mutrie by his mother after his father died in 2010.

The attorney general has not commented on how the weapon came to be in Cullen Mutrie's possession.

In the latest development in the court battle, Grant filed a motion Monday asking the court to compel Beverly Mutrie and her attorneys to provide information the plaintiffs are seeking about bank accounts owned by Beverly Mutrie, or jointly between Beverly Mutrie and her son.

They are also requesting information about whether Beverly Mutrie financed her son's legal fees while he was fighting past criminal charges.

According to Grant, Beverly Mutrie and her attorneys have also declined to provide information about the health care and mental health treatment Cullen Mutrie received before his death.

Grant has also asked McHugh to compel Beverly Mutrie to provide a copy of all estate planning documents relating to her late husband. Doing so would help the defendants to prove that one of the weapons in Cullen Mutrie's possession during the April 12 shooting came to him from his mother, they claim.

Grant has also asked for justices at the New Hampshire Supreme Court to be called in to review the case on an “interlocutory basis,” according to court records.
